The Canon de 75 mle GP II was a field gun used by Belgium during World War II. Cockerill mounted lengthened Canon de 75 mle TR barrels on ex-German 7.7 cm FK 16 gun carriages received as reparations after World War I. After 1940, the Wehrmacht designated captured guns as the 7.5 cm FK 234(b) and used them to equip occupation units in Belgium.
